Vision is the primary sense used by astronauts in space. Visual information is essential during critical phases of spaceflight, such as rendezvous and docking, robotic operations, and landing. The spaceflight environment has many significant effects on the visual and ocular system that can adversely affect astronaut performance, and may lead to long-term health consequences. On Earth, there are many conditions that, if not detected, may lead to irreversible vision loss or blindness. The human eye and vision system can be likened to a camera consisting of an optical lens system (cornea and eye lens), film (retina), and an image-processing unit (retina and visual cortex). The malfunctioning of only one of these components will impair vision.
